Rocking canes and methods of use

ABSTRACT

A walking assistance apparatus and a walking assistance kit comprising a first walking assistance apparatus and a second walking assistance apparatus are disclosed. Each walking assistance apparatus comprises a shaft comprising a first end and a second end, a reversible handle portion extending from the first end, and a base extending from the second end. The shaft comprises a sidewall. The base comprises a first portion positioned proximal to the second end of the shaft, a second portion positioned distal from the second end of the shaft, and a third portion positioned intermediate the first portion and the second portion. The base comprises an arc-shaped contacting surface extending at least along the third portion. The first portion of the base comprises an end portion that is substantially aligned with the sidewall of the shaft.

FIELD

The present disclosure relates generally to apparatuses and methods for assisting patients suffering from spine disorders, back disorders, and/or arthritis and, more particularly, relates to rocking canes and methods of using the same for assisting patients suffering from spine disorders, back disorders, and/or arthritis.

BACKGROUND

Patients with spine disorders, back disorders, and/or arthritis may experience pain during ambulation and/or standing. This pain may range from minimal to quite severe. In some instances, the pain may be so severe that the patients experience great difficulty ambulating and/or standing. One type of pain-causing disorder is spinal stenosis. Spinal stenosis is a narrowing of the lumbar (back) or cervical (neck) spinal canal, which causes compression of a patient's nerve roots. It is estimated that 1,000,000 people are currently suffering from spinal stenosis in the United States. The condition is usually more prevalent in senior citizens as back disks usually compress as patients age. Spinal stenosis may, at times, render many patients immobile, or partially immobile, due to pains experienced when ambulating and/or standing. Patients with spinal stenosis may attempt to minimize ambulation and/or standing during daily life to alleviate pain.

Four treatments are recognized by the Mayo Clinic to treat spinal stenosis. These treatments are medication, therapy, steroid injections, and surgery. Medications, such as anti-depressants, anti-seizure drugs, and opioids, for example, may be prescribed. Therapy may be used to provide patients with exercises that may help build strength and endurance, maintain flexibility and stability of the spine, improve balance, and/or control pain. Steroid injections, such as injecting a corticosteroid into the area of the back surrounding the constriction of the disks, for example, may help reduce the inflammation and relieve some of the pressure created by the constriction. Repeated steroid injections, however, may weaken nearby bones and connective tissues and, therefore, only a few injections are usually administered to a patient each year. Surgery is the most drastic form of treatment of spinal stenosis and may be relied upon if the above-referenced more conservative treatments are not successful or helpful.

The present disclosure provides a different type of non-surgical treatment for those suffering from spinal stenosis, back pain, arthritis, and/or related disorders. The present disclosure also provides walking assistance apparatuses, kits, and methods for patients having difficulty ambulating and/or standing.

In one embodiment, referring to FIGS. 8A and 8B, the walking assistance kit 100 is illustrated in use when a user 101 is ambulating over an ambulation surface 103 in the direction indicated generally by arrow 102. In various embodiments, referring to FIGS. 9A-9C, the progression of how the arc-shaped contacting surface or the contacting surface comprising an arcuate portion 46 of the base 16 of the walking assistance apparatus 10 contacts the ambulation surface 103 is illustrated when the user walks in a direction generally indicated by arrow 104. The walking assistance apparatus 10 (only one is shown for clarity) may be moved by the user between a first position 80 (FIG. 9A), a second position 82 (FIG. 9B), and a third position 84 (FIG. 9C) during ambulation. In the first position 80, the first portion 40 of the base 16 may be in contact with the ambulation surface 103. Also in this first position 80, part of the third portion 44, or the entire third portion 44, may also be in contact with the ambulation surface 103 depending on the curvature of the arc-shaped contacting surface or the contacting surface comprising an arcuate portion 46 of the base 16. In the second position 82, the third portion 44 and possibly a part of the first portion 40 and a part of the second portion 42 may be in contact with the ambulation surface 103. Again here, whether the part of the first portion 40 and the part of the second portion 42 contact the ambulation surface 103 in the second position 82 may be dependent on the curvature of the bottom surface of the base 16. In the second position 82, the shaft 14 may be in a vertical position, or in a substantially vertical position. In the third position 84, the second portion 42 may contact the ambulation surface 103. A part of the third portion 44, or the entire third portion 44, may also contact the ambulation surface 103 when in the third position 84. In view of the foregoing, it is illustrated how the walking assistance apparatus 10 may be “rocked” as the user moves in the direction indicated generally by arrow 104. In one embodiment, the bases 16 may act like a human foot that contacts the ambulation surface 103 from “heel to toe.” When referring to contact between the various portions 40, 42, and 44 and the ambulation surface 103, it will be understood that the bottom-most surface of the various portions 40, 42, and 44 will make such contact.

In various embodiments, another progression of how the arc-shaped contacting surface or the contacting surface comprising an arcuate portion of the base of the walking assistance apparatus contacts an ambulation surface is provided. The walking assistance apparatus may be moved by the user between a first position, a second position, and a third position during ambulation. In such an embodiment, the base may contact the ambulation surface from “toe to heal.” In the first position, the second portion of the base may be in contact with the ambulation surface. Also in this first position, part of the third portion, or the entire third portion, may also be in contact with the ambulation surface depending on the curvature of the arc-shaped contacting surface or the contacting surface comprising an arcuate portion of the base. In the second position, the third portion and possibly a part of the first portion and a part of the second portion may be in contact with the ambulation surface. Again here, whether the part of the first portion and the part of the second portion contact the ambulation surface when in the second position may be dependent on the curvature of the bottom surface of the base. In the second position, the shaft may be in a vertical position, or in a substantially vertical position. In the third position, the first portion may contact the ambulation surface. A part of the third portion, or the entire third portion, may also contact the ambulation surface when in the third position. As a result, the walking assistance kits of the present disclosure may be used with the second portion of the base facing in the direction of movement or the second portion of the base facing away from the direction of movement.

In some instances, back pain may be caused by disks being compressed. Shifting of body weight may help reduce the compression of the disks and, thereby, reduce back pain associated with disk compression. As such, the present disclosure, in part, provides a method of use for a walking assistance kit, wherein a user may continuously, or at least mostly, decompress back disks by applying a downward pressure on a first walking assistance apparatus and/or a second walking assistance apparatus during ambulation and/or standing. Such downward pressure may relieve back pain by decompressing the user's disks and allowing the user to ambulate pain free or with reduced pain. To achieve suitable disk decompression, at least one of the walking assistance apparatuses may be in contact with the ground at all times. In one instance, the walking assistance kit may be used by people suffering from, back pain or disorders, spinal stenosis, and/or arthritis to help them get back into their daily activities and achieve a healthier life style through exercise. The walking assistance kit may also help a user maintain a good posture while walking (e.g., less bending of the back).

In one embodiment, the present disclosure provides a method of assisted ambulation using the walking assistance kit 100. In various embodiments, referring to FIGS. 8A and 8B, the walking assistance kit 100 comprises the first walking assistance apparatus 110 and a second walking assistance apparatus 111, as described herein. The method may comprise the steps of gripping the reversible or bi-directional handle portions of the walking assistance apparatuses, placing the first and second walking assistance apparatuses in front of yourself in the desired direction of ambulation with the first portions of the bases in contact with an ambulation surface, and positioning the base of the first walking assistance apparatus further in front of yourself than the base of the second walking assistance apparatus or vice versa. In one embodiment, the first and second walking assistance apparatuses may be positioned in front of the user by about 5 to about 70 degrees, about 15 to about 60 degrees, about 20 to about 50 degrees, or about 25 to about 45 degrees, for example, with respect to a vertical axis of the user. The second portions of the bases may initially be up in the air (i.e., not in contact with the ambulation surface). The method may further comprise leaning in the desired direction of ambulation while applying a downward force to the reversible handle portion of the leading walking assistance apparatus and thereby the first portion of the base, taking a first step in the desired direction of ambulation thereby transferring contact with the ambulation surface from the first portion of the base to the second portion of the base of the first walking assistance apparatus, pushing off of the first walking assistance apparatus, and taking a second step, with your other foot, in the desired direction of ambulation thereby transferring contact with the ambulation surface from the first portion of the base to the second portion of the base of the second walking assistance apparatus. Additional steps may be taken in a similar manner.

In various embodiments, the method may further comprise maintaining the downward force on at least one of the reversible handle portions throughout ambulation and maintaining your elbows close to the sides of your torso. Such steps will allow for back disks to remain decompressed during standing and/or ambulation. In one embodiment, the method may further comprise removably attaching the first walking assistance apparatus with the second walking assistance apparatus when ambulation has ceased, when going up or down stairs, and/or when opening doors. The method further comprises positioning the end edges toward the direction of ambulation when going up stairs and positioning the end edges away from the direction of ambulation when going down stairs. During ambulation using the walking assistance kit, it may be best to walk at a normal pace without overstepping or overreaching with one of the walking assistance apparatuses. The normal pace may promote coordination, weight transfer (thereby promoting decompression of back disks), and posture. In one embodiment, a first walking assistance apparatus may be moved in unison, or substantially in unison, with a left leg of a user taking a step and a second walking assistance apparatus may be moved in unison, or substantially in unison, with a right leg of a user taking a step. It may also be helpful to keep your head up during ambulation with the walking assistance kit.

In one embodiment, a method of shifting a user's weight from a first walking assistance apparatus to a second walking assistance apparatus when using the walking assistance kit is provided. Each walking assistance apparatus may be designed or adjusted for a particular user's height such that a downward force applied by the user to the walking assistance apparatus may be maintained during standing and/or ambulation. In regard to the first walking assistance apparatus, the user's weight may be shifted from the first portion of the base, to the third portion of the base, to the second portion of the base and then the user may push off of the first walking assistance apparatus thereby transferring to user's weight to the second walking assistance apparatus. Then, in regard to the second walking assistance apparatus, the user's weight may be shifted from the first portion of the base, to the third portion of the base, to the second portion of the base and then the user may push off of the second walking assistance apparatus thereby transferring the user's weight back to the first walking assistance apparatus. Additional steps may be taken in a similar manner. As a result, the user's weight may continuously be shifted from one walking assistance apparatus to another, thereby maintaining the back disks in a decompressed state or in a substantially decompressed state.

In one embodiment, the walking assistance apparatuses of the present disclosure may comprise a locating assembly. Such a locating assembly may be similar to that available to locate keys. In one embodiment, a signal generator may send out a signal to a receiver on a walking assistance apparatus. The signal generator may have a button that, when depressed, causes the signal to be generated. Upon receipt of the signal, an audible sound or a visual display may be produced to allow the user to locate the walking assistance apparatuses.
